The design and manufacture of syringe moulds is closely […]
The design and manufacture of syringe moulds is closely related to plastic processing. The success or failure of plastic processing largely depends on the mould design effect and mould manufacturing quality, and the plastic mould design is based on the correct plastic product design.
The structural elements to be considered in the design of syringe plastic moulds are:
① Parting surface, that is, the contact surface where the concave mould and the convex mould cooperate with each other when the mould is closed. The choice of its location and form is affected by factors such as the shape and appearance of the product, wall thickness, moulding method, post-processing technology, mould type and structure, demoulding method, and moulding machine structure.
②Gating system, that is, the feeding channel from the injection moulding machine nozzle to the cavity, including the main flow channel, the flow distribution channel, the gate and the cold material cavity. In particular, the location of the gate should be selected so that the molten plastic fills the cavity in a good flowing state, and the solid runner and gate cold material attached to the product are easy to eject from the mould and be removed when the mould is opened (heat flow Except Daomo).
③ Plastic shrinkage and various factors that affect the dimensional accuracy of the product, such as mould manufacturing and assembly errors, mould wear, etc. In addition, when designing compression moulding and injection moulds, the matching of process and structural parameters of the moulding machine should also be considered. Computer-aided design technology has been widely used in plastic mould design.
